THREAD-GUIDE.

Specification of Letters Patent.

Patented Nov. 7, 1905.

Application filed March 22, 1905. Serial No. 251.443.

T0 at whom, it may concern:

Be it known that I, XAVER BOSSART, a citizen of the Republic ofSwitzerland, residing in Paterson, county of Passaic, and State of NewJersey, have invented certain new and useful Improvements inThread-Guides; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

My invention is an im rovement in threadguiding means for teXt' emachinery; and it has for its object to provide, in combination with arod, a member slidable thereon longitudinally thereof and comprising athreadguide, such arrangement permitting movement of the thread-guidelaterally with reference to the thread-feed line for adjustment or fortemporary removal from its normal position, so as to afford access toother parts of the particular machine in which the device is used.

Referring to the drawings, Figure 1 is aview of the device partly insection and partly in elevation. Fig. 2 is a similar view except that adifferent form of the thread-guide proper is illustrated. Fig. 3 is asectional view on the line a: :10 in Fig. 2. Fig. 4 illustrates acertain spring, and Fig. 5 illustrates a slight modification.

In said drawings, a is a rod formed with a longitudinal groove 1). Thethread guide member comprises a mounting, in the adaptation shown beinga sleeve 0, arranged-on said rod in such manner that while it may bemoved laterally such movement will not result from vibration or otherunintentional causes and the thread-guide proper, cl.

The thread-guide proper may be of any desired form, two different formsbeing shown It has a bore or bores e, into which snugly fits a stem orstems f, which is or are riveted into the sleeve 0, or, as shown inFig.5, a strip of the metal of the sleeve is cut out and turned off at rightangles to form a stem g. The sleeve is formed with an ori- 1 fice h,which receives a rebend '5, formed in a slightly-curved wire spring 3',Fig. 4. The body of {this spring is arranged in groove 1) and by bearingon the bottom of the same prevents the movement of the sleeve, exceptsuflicient force be applied thereto for that purpose. At the same timeby virtue of its engagement with the groove the spring prevents thesleeve from turning on the rod.

I do not wish to be limited to the precise I(gonstruction herein shownand described;

What I wish to claim, and desire to secure by Letters Patent, is

1. The combination of a rod, a threadguide member comprising thethreaduide proper and a mounting therefor slidab e on said rod, and aspring movable with and inclosed in the mounting and engaging said rod,substantially as described.

2. The combination of a longitudinallygrooved rod, a thread-guide membercomprising the thread-guide proper and a mounting therefor slidablelongitudinally on said rod,'and a spring movable with and inclosed inthe mounting and engaging said rod in the groove thereof, substantiallyas described.

3. The combination of a longitudinallygrooved rod, a thread-guide membercomprising the threaduide proper and a mounting therefor'slidablelongitudinally on said rod, and a spring inclosed in and movable withsaid mounting and engageable with said rod in the groove. thereof,substantially as described.

4. The combination of a rod, a threadguide member comprising thethread-guide proper and a mounting therefor slidable longitudinally onsaid rod, and a curved spring interlocked with said mounting andinclosed therein and having its ends engaging in said groove,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of March, 1905.

XAVER BOSSART.
